Maretron Submersible Pressure Transducer 0-3 PSI PTS-0-3PSI-02

Submersible Pressure Transducer 0-3 PSI

Maretron’s submersible pressure transducers indicate tank levels and can be installed directly in the tank. Please follow these instructions to mount and connect a submersible pressure transducer to an NMEA 2000® network via a Maretron FPM100 Fluid Pressure Monitor. Maretron recommends one of two methods for mounting a submersible pressure transducer in a tank: 1) without a restraining tube, and 2) with a restraining tube.

The submersible pressure transducers are designed for a tank with a 5-hole SAE J1810 fitting at the top. Install the mounting plate with cord grip onto the transducer cable, with the rounded hex section of the cord grip facing away from the transducer.

Lower the pressure transducer into the tank such that the transducer lies at the lowest point of the tank and tighten the cord grip to secure the cable. On a tank with a flat bottom, the transducer may slide from side to side with the motion of the vessel but will not rotate due to the stiffness of the cable. It is also possible to mount the pressure transducer inside a restraining or focus tube (sold separately, Maretron part number TFT-5H).

Pressure Transducer Mounting

Connect the two wires of the pressure transducer to a free pressure monitoring channel. Connect the red wire from the pressure transducer to the channel's positive (+) terminal and connect the black wire from the pressure transducer to the negative (-) terminal of the channel. The example in Figure 1 shows the pressure transducer connected to switch channel 0, with the white wire connected to "P0+" and the brown wire connected to "P0-." Submersible pressure transducers have a small plastic vent tube in the connecting cable.

Use a Maretron DSM Series Display (firmware 1.4.7 or higher) or a PC running Maretron’s N2KAnalyzer software (version 1.4.19 or higher) to configure the connected channel(s) on the FPM100.

Supply power to the NMEA 2000 network and verify that the pressure channel indicates a valid pressure reading.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
